TOP ROLL FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 414,224, dated November5, 1889.

Application filed March 14, 1888. Renewed April 2, 1889. Serial No.805,800. (No model.)

To all whom it may concern:

Be it known that I, WARREN T. KELLOGG, a citizen of the United States ofAmerica, residing at Cohoes, in the county of Albany and State of NewYork, have invented new and useful Improvements in Top Rolls forSpinning-Machines, of which the following is a specification.

My invention has relation to improvements in top rolls forspinning-machines, and the object is to provide improved means forholding the bosses 011 the spindle or arbor.

lVith this object in View my invention consists of a pliant and elasticwasher sprung on the projecting end of the spindle and arranged adjacentto the shoulder of the boss in position to keep it on its bearing.

I am fully aware that metallic spring-rings have been used for thepurpose of keeping the bosses from slipping off the. spindle, theserings being fitted in annular grooves on the spindle or sprung into achannel into the interior of the boss. Metal washers or keepers ofeither of the forms mentioned are liable to abrade the bearing-surfaceof the boss when it is removed from the spindle, and their applicationis inconvenient, and they do not serve to prevent the oil from leakingor wasting from the bearings of the bosses.

I have fully illustrated my improvements in the accompanying drawings,wherein- Figure 1 is a longitudinal central section of a top-rollspindle, the revoluble bosses, and my improved elastic washer. Fig. 2 isa similar view showing a short spindle and single boss. Fig. 3 is a viewof the washer.

Reference being had to the drawings, A designates the spindle on whichthe revoluble bosses are mounted. This spindle, when made for more thanone boss, is formed With shoulders 1 at the middle part, where the saddle is applied, to keep the bosses in their relative positions in thatdirection, and when the spindle is designed to carry but one boss eachend of the spindle is provided with a Washer and the boss thus kept fromslipping off when the spindle is removed from its bearings. Thebearing-seats of the bosses may be turned to slightly taper at each end,as seen in the draw ings, to form oil-channels, and in these bearingsare holes 2, in which is tightly packed some material adapted to holdoil and feed it to the bearing-surfaces of the parts.

B designates the bosses, which are of identical construction, whetherintended for use singly or mounted in pairs on the spindle. The middleand bearing-surfaces 3 are a straight polished bore, and the ends 4 arecounterbored to project over the shoulders at the middle of the spindleand over the bearing end of the spindle and over the elastic keeper orwasher, as seen in the drawings.

0 designates myimproved pliant and elastic washer or keeper. Thisconsists of an india-rubber band or similar material having theessentials of pliancy and elasticity and without the rigidity orflexibility of metals. These elastic washers are of such size as to bereadily stretched over the ends of the spindle, and are held in arrangedposition by the retractive force of the material. The bands or washersare set back on the spindle under the projecting counterbore of thebosses, and are thus protected from the saddle and serve, as stated, tohold the oil in the boss and prevent it from running out at the ends.The yielding character of the washer also prevents all abrasion of theboss and arbor such as takes place when the bosses are held on thespindle by metallic washers or bands. It will also be perceived that bythe use of a pliant and elastic band, keeper, or washer, the end of thespindle may be without the usual channel formed therein when a metallickeeper is used. These channels are objectionable, because they collectoil and hold dust, and thus cause friction and consequent wear of theparts.

My improved keeper or washer is not in contact with the boss, except,may be, at the end of the bearing, and is not carried with the boss inrevolving, and hence imposes no friction on the parts. The bands usedfor the washers are preferably of that character or kind of rubberprepared by the trade and known as anti-oil bands. These will stand formany months; but the common band will serve the purpose effectually forthe usual time (usually a month) the bosses are run before removing themto be cleaned. If it is desired to remove the boss from the spin dle,the elastic band may be very readily removed, when the boss will slideoff. The band maybe as readily replaced, and if it becomes 7 Worn a newone can be easily slipped on the spindle. A

I make no claim in this application to th special construction of thespindle with transverse oil-packing holes, as I have made that featurethe subject of another application for Letters Patent, Serial No. 267,144, filed on the 14th day of March, A. D. 1888.

My improved keepers or Washers are appli cable toany construction ofbosses, but are especially intended for use with light bosses.

\Vhat I claim is 1. The combination,with a tubular boss and the spindleof a top roll of a spinning-machine, of a pliant and elastic Washersprung on the end of the spindle, substantially as described, and forthe purpose specified.

2.: The combination, with a tubular boss formed with counter-bored ends,and the spin- 'end of the spindle and under the projecting counterboreend of the boss, substantially as described, and for the purposespecified.

In Witness whereof I have hereunto set my hand in the presence of twoattesting Witnesses.
